Y., ASSIGNOR TO JACOIBUS SCHOOL PRODUCTS 00., INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK INKWELL CLOSURE Application filed November 6, 1928. Serial No. 317,587.

This invention relates to an improvement in covers or closure caps intended for use upon ink-wells, ink-bottles or similar receptacles and it has for its object to provide a device of this character which shall be proved cover or closure is primarily intended for use upon ink-wellsor ink bottles, it will be understood that the same may be readily used upon bottles intended for con taining other liquids or powders, and I therefore do not limit my invention to any one particular application of the same.

Referring to the accompanying drawing:

Figure 1 is a plan view of one embodiment of my invention, showing the parts thereof in the position that they occupy when the cover is closed;

Figure 2 is a side elevation of the same;

Figure 3 is a view of the underside of the cover, showing the slide in a partly open position; i

Figure 4 is a sectional View on the line 44: of Figure 1, looking inthe direction of the arrows;

Figure 5 is a sectional view on the line 55 of Figure 1, looking in the direction of the arrows; and

Figure 6 is an enlarged detail in section of part of the cover and inner plate, showing the means utilized for retaining the inner plate within the cover.

Throughout the various views of the drawings, similar reference characters designate similar parts.

In the embodiment of my invention disclosed in the accompanying drawing, 1 indicates the cap or cover member which is preferably made of thin sheet metal. The same is provided with a fiat plate-like top 2 which has an integral peripheral flange 3 that extends downwardly from its side edges and is threaded so that the cap may be received upon the upper end of an ink-well or other suitable receptacle, a part of'which is diagrammatically illustrated at 5 in Figure 2.

The topplate 1 of the cover member is provided with an elongated opening 4 to permit the insertion of a pen into the well on which the cover may be attached, or if desired, to permit the contents of the vessel to be poured out when required, without the necessity of removing the cap from its position on the well or other vessel. This opening 4 is intended to be normally closed by a sliding closure plate 6 which is capable of sliding movement to cover or uncover the opening 4] c The sliding plate 6 is provided near its front edge with a pressed-up hump 7 in order that the sliding movement of the plate 6 across the opening 4 may be facilitated since said hump permits of ready engage ment with the finger or the pen-point of a pen seeking insertion into the ink-well.

The sliding plate 6 is maintained in a channehlike guide-way or groove 8 formed by distorting downwardly a portion of'a disk-like inner metal plate 9 which conforms in shape to the cover 1 and thus snugly fits within'the flange 3 of the coverand is fixedly held therein. 8 is so located on the plate 9 that it lies directly below the opening' in the cover member, and said guide-way is provided with a corresponding opening 10 which is located in registration with the opening 4. Thus, when the sliding plate 6 is moved rearwardly to uncover the opening 4:, it serves also to uncover the corresponding opening 10 in the inner plate member 9 whereby access to the contents of the vessel is had.

The inner plate member 9 is provided with a short perihpheral, downwardly extending skirt or flange 11 which fits closely within the flange At several spaced points the two flanges 3 and 11 are united The gulde-way or groove will be readily comprehended.

and said inner plate 9 acts to provide a guide-way for the sliding plate 6. The necessity therefore, of in any way piercing or lnutilziting the cover member 1 for the purpose ot, pr0viding retentive means for the sliding plate 6 is obviated, with the result that the finished 'cap presents asmooth unbroken appearance when viewed exteriorly.

From the foregoing, the many uses to which my improved closure cap may be put plied to an ink-Well it may be closed or opened with a simple sliding; movement thus requiring minimum of efiort. Then applied to other vessels, it-perinits the contents to be kept clean and sanitary since the vessel to which it is applied may be covered or unecvered in an instant.

Having described one embodiment of my invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope or" the HEDGXQQ claim.

hat I claim is r A closure cap for ink-wells having an outer zip-shaped nieinher provided with a downwardly extending peripheral threaded flange adapted to be received on a threaded ink-Well top, 21 similarly shaped metal inner member prov l with a shorter skirt-like fienge closely'fit ng wi nn that on the outer member and ring at the upper termination oi the threaded portion thereon, the flanges on both members being; punched together at spaced points, the inner member being provided with a (lOVViHVHlTily depressed clnnmeldike PTOUVG of uniform depth terminating; edje t diametrically opposite points on the thun e of the inner member, sai'tl inner and outer members having registering pen-receiving; openings and an imierforz te slide movable in the groove between the inner and outer members.
